Shaun Palmer, Olympic snowboarder, X-games champion, and "godfather of extreme sports" raced his heavily modified GMC Syclone up the 2003 Pikes Peak hillclimb. It was as badass as you thought it would be.

We don't get much engine noise from the 12 minute, 12.46 second run, but we do get a fittingly metalhead soundtrack. The Prince of Darkness approves!
